Product Details

“Phobic” about working with bacteria? This teacher-designed and student-tested kit starts with the basics and provides a significant microbiology laboratory experience that is both stimulating and fun. The purpose of the lab is to expose students to the fundamental procedures used by microbiologists to inoculate, culture, and analyze bacterial cultures. After learning basic bacteriological techniques, students determine whether a culture of E. coli is resistant, intermediately sensitive or sensitive to a series of five antibiotics. These are the same techniques originally used in hospital laboratories to determine the most effective treatment for infections.Sufficient nutrient agar, sterile Petri dishes, sterile applicator swabs, and antibiotic sensitivity disks are provided for 100 students working in pairs. An autoclave or pressure cooker as well as a live culture of E. coli are required but not provided with the kit.

Performance Expectations

MS-LS4-4. Construct an explanation based on evidence that describes how genetic variations of traits in a population increase some individuals’ probability of surviving and reproducing in a specific environment.
MS-LS4-6. Use mathematical representations to support explanations of how natural selection may lead to increases and decreases of specific traits in populations over time.
HS-LS4-5. Evaluate the evidence supporting claims that changes in environmental conditions may result in (1) increases in the number of individuals of some species, (2) the emergence of new species over time, and (3) the extinction of other species.
